This invention relates to an improvedriveting machine and especially to that portion of the riveting machine embodying an anvil and a work support cooperating therewith.

The object of the invention is to provide aV rivet'setting machine for setting bifurcated rivets in the soles of boots and shoes in such a manner that there will be a space between Vthe clinched prongs of the rivet and the upper face of the sole, the said rivet serving as a means, as hereinafter more fully set forth, for att-aching a metal shank to a sole.

Thev invention consists in the improved anvil and work support, and in the combination of the same with the positioning` and driving instrument-alities ofv a rivet setting machine, asset forth 1n the following speci- Vfication and particularly in the claims thereof.

Referring to the drawings Figure 1 is a front elevationof my im-V proved anvilA Y and work support shown in operative relation to the driver and rivet cary rier of a rivet setting machine similar to that vdisclosed inthe pat-ent to Josep'hjE. Perrault, No. 879,896, patented February 25, V1908, machine for setting rivets.

F ig. 2 is'a sectional elevationvtaken Yon the Y line 2 2 of Figure 1.

, y support.

Fig. 3 is a sectional elevation similar to Fig. 2, but showing the rivet carrier lowered and with the rivet about to be driven through the material by the driver.'

Fig. 4 is va detail section showing the rivet 'as it appears just after being clinched.

Fig. 5 is a detail section taken on the line v54-5 of Fig. 4. Y f Y Fig. 6is a perspective view of the work Fig.7 is a. plan view of a sole with the rivet inserted therein and a shank shown in full lines inthe position which it occupies when being attached to thel sole andV in dotted lines in the position in which it appears after being attached tothe sole.

Like numerals refer to like parts through- Y out the several views of Vthe drawings.

slide 12. is a rivet positioning arm pivoted at 18 to the carrier slide 12 and held normally in the position illustrated in -Fig` ure 1 by a spring 19 also fast to thecarrier' slide 12, all of this mechanismbeing old and' screw-threaded engagement with the frame 21. On the upper end of the anvil 20 is fixedly mounted a cap 23 having a hollow cyhndrical portion'V orneck 24. and a top 25.

The cap 23 is provided inthe top with aslot K 26 which extends throughthe top in alignment with the anvil 20and extending trans,-

versely thereof. The top 25 of the work supportis also provided with a groove 27 which extends transversely Aof the slot 26 upon opposite sidesy thereof, the'bottom of the groove27 being inclined downwardly from the upper face of the top 25 into `the slot 26.

VThe object of thev slot 26iis to allow the rivet prongs, after they have been clinched by the anvil, to* be withdrawn through the top ofthe cap.l w Y The/object of the groove 27 is `toprevcnt a portion of the material into which the rivet is drivenfrom being cut off by the edge of the slot, in which case it wouldbe possible to rotate the rivet'in the material in which it is set and this wouldbe very undesirable as it would free one end of the shankv28. Y

The shank 28 is positioned upon the sole 29 .as illustrated in Fig. 7. Said shank is provided with a slot 30 extending longitudinally thereof, and when it is desiredto fposi.V

tion the shank upon the sole and attach it thereto, it is first placedin the position illus'- trated in full lines, Fig?, and the prongs 81 of the rivet 32 are then in alignmentwith the slot 30'. v Upon rotating the shank 28 from the full line to the dotted line position, Fig. 7, the' prongs of the rivet will be positioned across the slot 30, the tack 83 is then inserted through the shank andinto the soley 29 to hold the other end of the shank in position on the sole. The slotBOallows play of the free end of the shank relatively to the sole when the shoe is being used.

A' reciprocatorymotion is imparted to the Patent` and the operator pla-ces the sole 29 u aon the top of the work support 23, the so e er; ending, longitudinally thereof, from right to left in Figure 1. He then places his foot upon the treadle and the rivet carrier and driver move downwardly from the position, illustrated in TEig 2 to that illustrated in Fig. '3. The arm 17 tips upon thel pivot 18 and is withdrawn from between the v prongs of the rivet. The fingers 18 'and 14 are spread apart by. the downward movement of the driver 1.1 and by the head of the rivet, so that the prongs of the rivet are driven through the material of the sole 29 and are clinched or spread outwardly 'as illustrated in Fig. Llby the anvil 20. The position of the rivet relatively to the material' of the sole is illustrated in Fig. i and in v5, Fig. particularly illustrating how the material' of the sole is pushed down into the groove 27 on opposite sides of the slot- 26 without cutting itoff.

lli/Then the driver l11 and carrier slide 12 have moved upwardly together with the rivet carrying fingers 13 and 14 and the arm 17, the parts assume again the position illustrated Vin Fig. 1 and the sole 29 is removed from the machine. Now the sole has a rivet 82 firmly attached thereto with the prongs 31 of the rivet extending transversely of the sole as illustrated in F ig. and ready to have a shank attached to the sole in the manner hereinbefore set forth.

1 claim z- 1. A rivet setting machine having, in coinbination, an anvilv and awork support eX- tending across-the top ofV said anvil, the work support being provided with a slot eX- tending transversely of the anvil and; with a' groove in its upper-face intersecting said slot on opposite sides thereof.

2. A rivet setting machine having, in combination, a stationary anvil and a work support linedly mounted on the upper end thereof and extending across said upper end, the work support being provided with a slot ed on and extending across the upper end y thereof and yconstituting a work support, theV cap being provided with a slot`1n its upper end extending transversely of the anvil and with a groove in its upper face intersecting said slot onv opposite sides thereof. V

4. A fastener setting machine having, in combination, an anvil, and a work support positioned thereabove provided with a slot extendingtransversely of the anvil through which the end of the inserted fastener may pass and having a kgroove extending transversely of the slot on'its upper face, the portions of the groove lying on the opposite sides of the slot being provided with inclined bottom surfaces whereby to provide surfaces upon which the work may be pushed byy thefinserted fastener .without danger of shearing action thereon.

A rivet setting machine having, in combination, an anvil cnd a` work `support extending across the top of said anvil, the work support being Vprovided with a slot eX- tending transversely of the anvil and with a groove in its upper face intersecting said slot on opposite sides thereof, and rivet positioning and driving instrumentalities adapted to insert a two-pronged rivet in material positioned on said work support and to spread the prongs of said rivet, againstsaid anvil and spaced apart from said material by the top portion of said work support.

6. A rivet setting machine, having,` in combination, an anvil and a work support fixedly positioned thereon extending across and adjacent thereto, the work support being yprovided -with a slot extending through the top thereof and transversely of the anvil and with groove in its upper face inter'- secting said slot on opposite sides thereof, and: rivet. positioning and drivingl instruinentalities 'adapted to insert a bifurcated rivet in materialY positioned Von said work ln testimony whereof I have hereunto set y my hand.
